WINDOW-GLAss-GLEANING DEVICE.

i Applicationled March 14, 1911. Serial No. 614,361.

Be it known that I, EDWARD F. SCHOEN- DoRrER, citizen ofthe United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain newl and useful Improvements in Window-Glass-Cleaning Devices, of which the following is 'a specification.

My invention relates to improvements in window-cleaning devices, and more particularly to such devices -as are employed for cleaning the Windows of a moving vehicle, such as an electric trolley car or automobile, from adhering snow or rain.

My invention will be briefly ,explained as applied to the wind-shield oigan automobile; making reference to it-sluse, as well, upon-the window of a trolley car. My said improvements relate especially to the means for adjusting the device to `different thicknesses of glass and different window frames; to the means for securing an even pressure of the wiper upon the Asurface of the glass; to the means for eifecting both radial and lateral movement of said wiper; to the means for permitting'the lateral travel of the deviceupon the supporting rail without injuring or marring the same; and to other details which will be more fully set forth in connection with the accompanying drawings, wherein zv Figure 1 is a view in elevation of the rear or inner face of a model wind-shield to which my improvement is applied for illustrative purposes; Fig. 2 is a vertical seotional view thereof; Fig. 3 is an enlarged median sectional view of the device, partly broken away; Fig-t is another fragmentary view of the device partly assembled, particularly showing the spring and mounting rollers; Fig. 5 is a top view; Fig. l6 an end view; Fig. 7 a side view of the wiper or cleaning-member; Fig. 8 is a rear view of va Window-frame to which my pivoted cleaning device is applied;'Fig; Slis a fragmentary view, partially in .vertical section and upon an enlarged scale, better illustrating the slide and spring; Fig. 10 is a yfront view, partially in section, showing the slot for accommodating the bearing-sleeve, and Fig. 11 is another fragmentary view, showing the slide and spring.

Throughout the several figures of the drawings I have employed the same charac-I ters of reference to indicate similar parts.

Referring first to Figs. 3 and 9, wherein PatentedMay21,1912.

there are shown in enlarged detail the sevl eral parts of my improvement, it will be n0- ticed that the wiper or cleaner a is mounted upon a round, rectangularly -bent rod b which passes through the sleeve c, forming a pivotal mounting for the wiper. Said sleeve c is provided with a thumb-nut c .which makes the same adjustablev to accommodate various top or side rails whereon the device may be mounted. Thev protruding end of rod has an adjustable arm dsecurely mounted thereon by means of the setscrew cZ, this arm carrying an adjustable bearing-roller cl2 and support d.

lThe above described parts formthe elements of the window-cleaning device, which may either be mounted within the side-rail as indicated at w, Fig. 1, and shown in Fig. 8, or these members, instead, may be applied to the roller mounting which also forms a part of my invention. The latter comprises a U-shaped spring e Within frames or slides,

vertically slotted at e, whichv receive the sleeve c, which has a vertical adjustment Within-the duplicated slides f, f, for acco-m- `modating different sizes or shapes of toprails, as respectively indicated in Figs. l, 2, 3 and 4. These slides f, f, respectively carry the lateral rollers f, f', and the extended.

feetv f There is also provided an upper roller c surrounding sleeve c, and a hinged bifurcatedr member e which is adaptedl to embrace the rod d, as indicated in Figs. Q- and 3, to prevent its rotary movement; or it may be swung into the plane of the' extended limb of spring e in order to free the said arm, as desired. In addition to these details, I may valso explain the following preferred features of construction, to which, however, my lnvention 1s not necessarily restrictedz--The wiper a consists of two stampings a centrally slotted at a2 and provided with a recess a3. Between these stampings there is secured a rubber strip at, which may readily be renewed by removing screws a. "Within the recess a3 there is provided a collar b', held in place on rod b by its set/-screw b. A pin or stud b2 screwed into rod -b normally lies within the slot a2 of the wiper a, which, of course, may be of any suitable length, as indicated b the Abroken away portions inFigs. 3, an 7.

With this device mounted uponthe toprail g of a wind-shield, as in Figs. 1 and 2, it 5 will nowbe understood how it may be used, either for cleaning an arc-shaped portion of the window, or for moving the Cleaner from side to side.; thus with rod d held from turning by means of the bifurcated member e, the entire device may be moved bodily from one side of the wind-shield to the other, sweeping a path tlie 'width of wiper a entirely across the same. The position of the wiper may be adjusted upon Vthewind-shield merely by releasing the setscrew b and sliding the collar downward or upward along the rod b, whereon it may again be secured in adjusted position. In order -to sweep the wiper or cleaning-member through an arc, it is necessary merely to swing the member e to the position shown in Fig. 4, when said wiper may be moved by means of rod d through an arc, as indicated by the dotted lines in Fig. 1. In order to secure an even pressure of the wiper a against the glass, the bearing roller d may be adjusted lengthwise of roddso that said roller engages the glass at the point desired, and its pressure may be varied by altering the, angular position of said bearing roller on rod d, through the said set-screw da. The wiper a in. addition may be turned out of engagement-with the'glass, if desired, merely by releasing the screw b, sliding the 35 wiper the length of slot a and turning it so that the sto or stud b2 will lie within the angular endp portion of said slot a2. As shown in Figs. 3 and 4, the rollers are provided both with concave and flattened .surfaces, so that either a fiattened or rounded top-rail of a wind-shield may be suitably accommodated, while the sprin e permits, considerable variation in the thickness of these parts. However, as features of my invenf tion are not limited to wind-shields, I may refer to the use. of-the same in connection with the side or top rail of an ordinary window,'such as is required for the motorman `of a trolley car. Thus at av, Fig. 1, the devices provided for lateral travel of the wiper are shown as havin been dispensedwith and the sleeve or ot er suitable bearing is Vprovided in the side-rail for rod b, while rod d (shown broken away)2 is attached to its protruding end. In this position, of course, the wiper is afforded merely an arcshaped path, but for ordinary use this is entirely sufficient. The feature of adjustment provided by adjustably mounting the actuatmg-rod d upon the angular extension of rod b, affords a considerable accommoda- ,ftion for various thicknesses of frame and glass, while the pressure exerted by the' wlper may readily be altered, as desired, by adjusting the bearing'roller in its angular -of a rod forming a' pivotal mounting therefor, an actuating-member adapted to be ad- 75 ju'stably secured upon the extended end of said rod, and -a bearing-roller provided upon 4the actuating-member for engaging the Window glass` opposite' the wiper, substantially as set forth. Y p

2. In a window-cleaning device, the combination'with'a wiper of an angularly-bent rod forming a pivotal mounting for said wiper, an 'actuating-member adjustably secured upon the extended vangularly-bent end of the rod, means for holdin it in adjusted position thereon, an adjustab e roller mounting upon the actuating-member, and a roller or wheel for bearing upon the 'window glass opposite the wiper, substantially as set forth.

3. In a window-cleaning device, thel combination with a wiper adapted to bear upon one side of the Window of an actuating-member pivotally Jconnected with said wiper and extending adjacent to the'opposite surface 95 of the glass, means for temporarily withholding the parts 4from pivotal movement,

4. In paratus of the class described, the combination with a U-shaped spring of a pivoted cleaning device connected therewith, comprising a wiper.adapted to bear upon one side of the glass, and an actuatingmember positioned adjacent to the other side thereof, a frame therefor and roller bearings adapted to travel upon a supporting rail, substantially as set forth.

5. In aA window-cleaning device, the combination with separable metal parts affording a tubular slotted` sleeve provided with depending edges, of a rubber strip engaged between saidl edges, a. rod mounting the same for pivotal movement, a' stud lying within the slot, an adjustable collar retaining lthe device in position upon the rod, and an actuating-member for imparting pivotal movement to said device, substantially as set forth.

6. In a window-cleaningdeviceoftheclass described, the combination with an 'L-shaped rod' of a` pivotal mounting therefor, awiper positioned upon the free end of said rod, an

actuating-member adjustably secured to the pivoted end of the rod, a bearing-roller thereon; said wiper and bearin roller being designed to press opposite eac other upon opposite sides of a window glass; and means for adjustably securing the rod and actuat- 130 ing-member for common pivotal movement, whereby different thicknesses of glass and frame may be accommodated, substantially asset forth. y
